HydroMax Seal – SPW682-131
HydroMax Seal – SPW682-131
Advanced Stationary Cartridge Seal for API Plan 31 Systems with Restriction Bush Technology
The SPW682-131 from HydroMax Seal is a high-performance single-cartridge mechanical seal, engineered to meet the stringent requirements of API682 standards for critical Oil & Gas sector applications. Designed for compatibility with API Plan 31 systems on API610 V8 and later pumps, it delivers outstanding sealing efficiency in services involving suspended solids and abrasive process fluids.
This complete cartridge seal integrates a vortex breaker-equipped gland, along with a dual outboard restriction bushing system—featuring both segmented and floating restriction bushings—to ensure fluid stability, pressure regulation, and improved wear resistance.
Product Description
Design Features
- Flush port configuration tailored for Plan 31 — ensures flush fluid containing particles does not ‘shot blast’ the stationary seal face
- Quench and drain ports support Plan 62 and Plan 52 systems, with ian ntegrated deflector directing steam or buffer fluid to the inboard faces
- Large ½″ NPT seal port orifices for effective flow and system integration
- Integral vortex breakers in the gland plate reduce turbulence and protect sealing interfaces in slurry and particulate applications
- API682-compliant radial clearances for optimal sealing alignment and reliability
- Monolithic seal faces enhance thermal stability and wear resistance in high-temperature environments
- Self-aligning stationary seal face design, optimized for high-speed performance
- Multi-spring layout, with springs isolated from the process fluid to extend seal life
- Unique segmented + floating restriction bush combo ensures superior pressure control and outboard sealing security
- Fully compatible with HydroMax Seal’s Plan 31 Cyclone Separator System and Sample Collection Pot
